谁说一定要用GDI+了……纯控件也能整出类似效果。
好吧，能多难看就有多难看了。
每个段位都是用Panel做的， 横向 （10,2） 纵向（2,10） ，只是为了让他变成一根线。
1
2 3
4
5 6
7
这样子的格式。
每个显示的数字都是以UserControl的方式定义的。
然后使用
- C# code
private void Turn(int[] allPorts, int[] turnOffPorts, TurnTo turnTo) { bool to = turnTo == TurnTo.On ? true : false; foreach (int i in turnOffPorts) { this.Panels[i].Visible = to; } IEnumerable<int> turnOnPorts = allPorts.Except(turnOffPorts); foreach(int i in turnOnPorts) { this.Panels[i].Visible = !to; } }这样子的方式来控制段位的显示与否……。
于是一个混乱的段位显示器诞生了。
后面跟一段瞎眼代码，因为属于数据定义，所以略显繁琐
- C# code
public class NumberFactory { private static Dictionary<int, NumberRule> portsRule; public static Dictionary<int, NumberRule> PortsRule { get { if (portsRule == null) { portsRule = new Dictionary<int, NumberRule>(); portsRule.Add(0, new NumberRule { Ports = new int[]{ 4 }, TrunTo = TurnTo.Off, Source = 0 }); portsRule.Add(1, new NumberRule { Ports = new int[] { 3,6 }, TrunTo = TurnTo.On, Source = 1 }); portsRule.Add(2, new NumberRule { Ports = new int[] { 2,6 }, TrunTo = TurnTo.Off, Source = 2 }); portsRule.Add(3, new NumberRule { Ports = new int[] { 2,5 }, TrunTo = TurnTo.Off, Source = 3 }); portsRule.Add(4, new NumberRule { Ports = new int[] { 1,5,7 }, TrunTo = TurnTo.Off, Source = 4 }); portsRule.Add(5, new NumberRule { Ports = new int[] { 3,5 }, TrunTo = TurnTo.Off, Source = 5 }); portsRule.Add(6, new NumberRule { Ports = new int[] { 3 }, TrunTo = TurnTo.Off, Source = 6 }); portsRule.Add(7, new NumberRule { Ports = new int[] { 1,3,6 }, TrunTo = TurnTo.On, Source = 7 }); portsRule.Add(8, new NumberRule { Ports = new int[] { }, TrunTo = TurnTo.Off, Source = 8 }); portsRule.Add(9, new NumberRule { Ports = new int[] { 5 }, TrunTo = TurnTo.Off, Source = 9 }); } return portsRule; } } }[解决办法]
mark下，有时间我也试验下看看。

好！
。。还有7段码的分布是这样的
a
+----+
f| g |b
+----+
e| |c
+----+ . dp（小数点）
d
一般用一个byte的掩码来表示每段的「亮」「灭」（小数点一般在bit7），根据共阴和共阳显示上有区别（取反可以互换）
比如数字2，如果1为「亮」，那么2的段就是「a b d e g」，掩码是「X1101101」（我从高位往下a→g）
然后你可以在显示里用一个flag 00000001 不断左移来点亮每段。。
以后需要改变字符直接就传入你设计的掩码就行了。。MVC分离。。。

敢让它显示中文咩？

建议使用七段 LED 数字电路译码器的方式去处理数据
七段 LED 0～9 数字真值表
- C# code
A, B, C, D 表示数字的各二进制位a, b, c, d, e, f, g 表示 LED 的各段，为 1 时该段显示，为 0 时该段不显示 a ####### # # b f # g # ####### # # c e # # ####### d+---+---+---+---+---+ +---+---+---+---+---+---+---+| | A | B | C | D | | a | b | c | d | e | f | g |+---+---+---+---+---+ +---+---+---+---+---+---+---+| 0 | 0 | 0 | 0 | 0 | | 1 | 1 | 1 | 1 | 1 | 1 | 0 |+---+---+---+---+---+ +---+---+---+---+---+---+---+| 1 | 0 | 0 | 0 | 1 | | 0 | 1 | 1 | 0 | 0 | 0 | 0 |+---+---+---+---+---+ +---+---+---+---+---+---+---+| 2 | 0 | 0 | 1 | 0 | | 1 | 1 | 0 | 1 | 1 | 0 | 1 |+---+---+---+---+---+ +---+---+---+---+---+---+---+| 2 | 0 | 0 | 1 | 1 | | 1 | 1 | 1 | 1 | 0 | 0 | 1 |+---+---+---+---+---+ +---+---+---+---+---+---+---+| 4 | 0 | 1 | 0 | 0 | | 0 | 1 | 1 | 0 | 0 | 1 | 1 |+---+---+---+---+---+ +---+---+---+---+---+---+---+| 5 | 0 | 1 | 0 | 1 | | 1 | 0 | 1 | 1 | 0 | 1 | 1 |+---+---+---+---+---+ +---+---+---+---+---+---+---+| 6 | 0 | 1 | 1 | 0 | | 1 | 0 | 1 | 1 | 1 | 1 | 1 |+---+---+---+---+---+ +---+---+---+---+---+---+---+| 7 | 0 | 1 | 1 | 1 | | 1 | 1 | 1 | 0 | 0 | 0 | 0 |+---+---+---+---+---+ +---+---+---+---+---+---+---+| 8 | 1 | 0 | 0 | 0 | | 1 | 1 | 1 | 1 | 1 | 1 | 1 |+---+---+---+---+---+ +---+---+---+---+---+---+---+| 9 | 1 | 0 | 0 | 1 | | 1 | 1 | 1 | 1 | 0 | 1 | 1 |+---+---+---+---+---+ +---+---+---+---+---+---+---+
